Approximation is done by building a dominators tree for the heap graph.

Removed:
- reachable size (it is useless, after all);

paths in a hash map);

Make class BitField able to use 32 bits of a uint32.
...
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.
This happened when instantiating a bitfield BitField<T, shift, size> with
[shift=0, size=32] or [shift=31, size=1] or more general any
[shift=X, size=32-X]
As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

Remove the different length string types
...
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.
On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

Implement tick events compression in a log file.
...
Two techniques are involved:
- compress repeated line ends (common stack beginnings) by using back references;
- do RLE compression of repeated tick events.
This gives only 5% size reduction on benchmarks run, but this is because tick events are only comprise 10% of file size. Under Chromium winnings are bigger because long repeated samples of idleness are now compressed into a single line.
Tickprocessor will be updated in the next patch.

X64: Disabled RSet in 64-bit mode.
...
Made a few more places use intptr_t instead of int for pointer arithmetic.
Ensure that objects have a declared size that matches heap object alignment.

Add a script cache to the debugger
...
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.
Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.
Make the ComputeIntegerHash globally available.
Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

Optimize the scope creation code by lazily allocating the hash maps

for dynamic variables (only do it for the scopes that need them).

Introduce two separate classes of processor detection:
...
- TARGET, the architecture we will generate code for.
This is brought it from the build system.
- HOST, the architecture our C++ compiler is building for.
This is detected automatically based on compiler defines.
This adds macros for 32 or 64 bit, and cleans up some
include conditionals, etc.
